We look at the division of 891619 by 9 
We want to figure out the number of times 891619 can be divided by 9.

On to step 1:
8 divided by 9 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 9

On to step 2:
If we divide 89 by 9, we get 9 and a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Deduct 81 from 89 and we're left with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 9

Going ahead to step 3:
The number 9 fits into 81 9 times, leaving a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 99.0
The remainder is 0 after subtracting 81 from 81.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 9

On to step 4:
6 divided by 9 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 990.0
If we take 0 away from 6, we end up with 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 9

Going ahead to step 5:
When dividing 61 by 9, we get 6 with a remainder of 7.
Use 6 as the next digit of our solution. 
Result so far: 9906.0
The remainder is 7 after subtracting 54 from 61.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 9

Step 6:
When dividing 79 by 9, we get 8 with a remainder of 7.
Use 8 as the next digit of our solution. 
Result so far: 99068.0
If we take 72 away from 79, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
9 can be fit into 70 7 times, resulting in a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 99068.7
If we take 63 away from 70, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 8:
The number 9 fits into 70 7 times, leaving a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 99068.77
If we subtract 63 from 70, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Our division results in 99068.77 with a remaining 0.007.
